\n" ); document.write( "x+y+2z=8
\n" ); document.write( "x+y+5z=11
\n" ); document.write( "x+6y+4z=30
\n" ); document.write( "---
\n" ); document.write( "Subtract the 1st from the 2nd to get:
\n" ); document.write( "Subtract the 1st from the 3rd to get:
\n" ); document.write( "x+y+2z=8
\n" ); document.write( "0+0+3z=3
\n" ); document.write( "0+5y+2z=22
\n" ); document.write( "-------------------
\n" ); document.write( "Solve the 2nd to get z = 1
\n" ); document.write( "Substitute into the 3rd to get
\n" ); document.write( "0+5y+2 = 22
\n" ); document.write( "5y = 20
\n" ); document.write( "y = 4
\n" ); document.write( "------------------
\n" ); document.write( "Substitute into 1st to get:
\n" ); document.write( "x+4+2=8
\n" ); document.write( "x = 2
